Performed preventative maintenance for a Lennox heat pump model #XP14-036-230-10, serial #5814L07199. Upon arrival I powered the system down and removed the access panels. The evaporator coil’s are clean and in good condition. Tested the drain pan and drain line with several bottles of water to ensure that there are no leaks or clogs. Checked all electrical connections to ensure that they are secure and in good condition. Dispatch stated that the homeowner replaced the air filter a couple weeks ago however it is very dirty so I installed a new 20x20x1 air filter. I re installed the access panel and called for heat. The system started without any issues. The blower motor amp draw is 1.8. The heat pump coils are clean and in good condition. The heat pump amp draws are .98 for the fan and 8.7 for the compressor. The refrigerant pressures are within normal range. The system is operating properly at this time.
